Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

Drug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

Deep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

Stabilization of Pd Active Sites by Defective NaY Zeolite Framework for Enhanced Stability in Dimethyl Carbonate Synthesis

EcoEnergy, EarlyView.
A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.
